Nationalism and Unification
Nationalism united Italy and Germany and challenged empires.
About this topic
Nationalism is the belief that people who share a language, culture, history and territory should form their own nation-state and be loyal to it. Spread by the French Revolution and Napoleon, it became a leading force in the 1800s, creating new countries by unifying divided peoples, and breaking up multinational empires such as Austria-Hungary and the Ottoman Empire.
Italy had been split into many states. Count Cavour, prime minister of Piedmont-Sardinia, used diplomacy and wars, while Giuseppe Garibaldi's Red Shirts conquered Sicily and Naples in 1860, and Italy was unified by 1861, with Rome added in 1870. Germany was unified by Otto von Bismarck of Prussia through his policy of blood and iron: wars against Denmark, Austria (1866) and France (1870 to 1871), with the German Empire proclaimed in Versailles in January 1871.
Nationalism produced pride, national anthems, flags and shared education, but also rivalries, militarism and conflict with minorities, and it was a cause of World War I, especially in the Balkans. Example: Bismarck used the Ems telegram to provoke France into war and rally German states. Misconception: nations are not purely natural; they are built partly by stories and institutions. Today nationalism still shapes independence movements and politics.
